This is a simple effective upgrade for an RO system. It extends the life of your DI resin by allowing the first DI to be completely depleted before being replaced. It is also an easy way to add a DI stage to a RO unite that doesn't have one.

Great way to get TDS to 0By Nanoman28g on 12/11/2014

I had been using a three stage RO unit for years with a TDS reading of 10, but most people say that is not ideal for reef tanks, so I went ahead and installed this DI unit, which brought my TDS down to 0. Great product and very easy to install.

I had a BRS 5 stage system already, but added this canister to get the most from my DI resin. Even when the resin has changed color, it still has a little bit of life in it, so this way I can stretch my DI dollars a little bit. It's identical to the canisters I already have and as an added bonus - it came already full of resin! Bonus!

good dealBy chillermikeon 11/15/2014

I purchased this because I wanted to get the most out of my resin. I added it to my existing 5 stage system. When the 1st di changes all the way to brown the second one is picking up the slack. At that point simply change the cartilage and add new resin to the depleted one. No waste I get the most out of the resin for a 40.00 dollar investment and by the way you get 13.00 dollars worth or resin with the canister kind of a no brainer you are only paying 26.00 for the canister such a great deal.

Easy to install. This 2nd unit will prevent producing TDS water greater than 0 for my reef tank when the first unit is exhausted.

A must have for your R.O. unit.By Michaelon 9/2/2014

Instantly solved my TDS problem. I had been struggling with TDS readings from 3-10 for several months. New filters did not solve my problem. I installed the BRS DI Canister and my TDS went to zero. As usual with BRS, the item was top quality and shipping was fast.

Works great!By Vanon 6/1/2014

I have an RO filtration system at home for drinking water. It's a great system but not good enough for tank water IMO so I decided to add this canister. Installation was a breeze - I tee'd off the final output of the RO system to this DI canister and so far, it works great! TDS went from 15-20 to a solid 0 and has remained this for months now. Very happy with it and my fish/corals are having a blast as well.

After my RO unit it was still at 70 TDS. This unit pulled it down to 0 and has made over 100 gallons so far keeping my fish and coral very happy!
